To all whom it may concern Be it known that I, IRA E. CLUM, a citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have invented a new and useful Anchor for Posts, Poles, &c., of which the following is a specification.

The present invention appertains to anchors for telegraph and telephone poles, fence posts, and the like, and aims to provide a novel and improved device of that character adapted to be planted or embedded in the soil with the anchor rod, for anchoring the guy or stay cable or wire of a pole, post, or the like. I

It is the object of the present invention to provide an anchor of the nature indicated comprising a conical casting, the exterior surface of which is provided with novel means for resisting the tendency of the anchor to become withdrawn from its position in the soil, or to prevent the anchor from being displaced when once it is planted or embedded in the soil.

lVith the foregoing general objects outlined and with other objects in view, which will be apparent as the nature of the invention is better understood, the present invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a side elevation of the improved anchor. Fig. 2 is a central section thereof, illustrating the lower end of the anchor rod attached thereto.

In carrying out the present invention there is provided a conical casting or body 1 of suitable metal or material, which is provided with an aperture or opening 2 in its apex for the passage of the lower end of the anchor rod 3, the casting or shell 1 being provided with a flat inner shoulder 4 at its apex against which the nut 5 is adapted to seat, when the nut is threaded onto the lower end of the anchor rod. The surface of the shoulder 41 is smooth and of greater area than the cross sectional area of the nut 5, in

order that the nut 5 may rotate freely with the anchor rod 3, should the said rod be rotated for any reason whatever. This is of especial advantage when the anchor has been embedded in the soil, in order to prevent the nut 5 from being unscrewed by rotating the anchor rod 3, the upper end of which is exposed or projected above the surface of the soil for the attachment of the usual cable or wire guy or stay.

In order to effectively prevent the casting or shell 1 from being drawn outwardly or upwardly from its position within the soil, the exterior surface of the shell 1 is provided with an annular series of triangular ribs 6, the bases of which are spaced slightly above the bottom or periphery of the shell, and the apices of which project toward, but terminate short of, the apex of the shell. It will be noted that the sides of the triangular ribs 6, form inverted V-shaped portions having downwardly tapering passages therebetween, while the bases of the ribs 6 form upwardly facing shoulders between the sides of the said ribs 6. It will be observed that the channels or passages between the sides of the ribs 6 decrease in width from their upper ends, or from the apices of the ribs 6, to their lower ends, or to the bases of the ribs, which is of advantage for the purpose hereinafter set forth.

The exterior of the shell is also provided with lugs 7 within the ribs 6, and which form upwardly facing shoulders, which complement or cooperate with the shoulders formed by the bases of the ribs, as will hereinafter be more fully set forth.

In practice, to plant or embed an anchor of the present character, a hole is drilled or dug in the soil, of a diameter approximately equal to the diameter of the shell 1. The anchor rod 3 is then engaged to the apex of the shell 1, as above intimated, and the shell, together with the anchor rod, is inserted into the aforesaid hole, the shell 1 being seated upon the bottom of the hole. The hole is then filled and the soil is packed 0r tamped into the hole over the shell 1. The usual cable or wire guy or stay may then be attached to the upper end of the anchor rod 3, in the usual fashion, so as to brace the telegraph or telephone pole, fence'post, or the like, as is well understood in the arts.

After the device has been planted o-r embedded in the soil, the tensile strain or draft created upon the guy and anchor rod, will have a tendency to draw the anchor outwardly, it being observed that the conical form of the shell will prevent the anchor 5 from being displaced laterally inasmuch as the conical form of the shell will tend to maintain the shell in coaxial relation with the anchor rod. The upward movement of the shell is impeded due to the provision of ribs and lugs upon the exterior surface of the shell, it being noted that if there is a tendency to draw the shell upwardly, the soil between the ribs, or the sides of the ribs, will be forced downwardly, and will become packed between the lower ends of the sides of the triangular ribs, or within the lower contracted ends of the channels between the ribs, which will have a tendency to arrest the outward movement of the shell. Furthermore, the upwardly facing shoulders provided by the lugs 7 will also engage the soil so as to impede the upward 1110Vn1811l3 of the shell, which is also true of the shoulders formed by the bases of the ribs. The shoulders formed by the lugs 7 and by the bases of the triangular ribs, are parallel and arranged one above the other, in order that they will cooperate to effectively impede the upward movement of the shell. As a result, 30 the shell will maintain its position within the soil, notwithstanding the tensile strain or draft created upon the guy cable, and anchor rod.

The present anchor may be employed for various purposes, as will be apparent to those versed in the arts. The ribs (3 and lugs is claimed as new is 1. An anchor embodying a conical shell, the exterior surface of which is provided with an annular series of channels, which decrease in width from their upper to their lower ends.

2. An anchor comprising a conical shell, the exterior surface of which is provided with inverted V-shaped ribs arranged in an annular series.

3. An anchor comprising a conical shell, the exterior surface of which is provided with an annular series of triangular ribs, the apices of the ribs projecting toward the apex of the shell.

4. An anchor comprising a conical shell, the exterior surface of which is provided with an annular series of triangular ribs, the apices of which project toward the apex of the shell, and the bases of which are parallel with the periphery of the shell, and the exterior surface of the shell being provided with lugs within the said ribs forming up.- wardly facing shoulders.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
